I Application filed November '10, 1914. Serial No. 871,430. v

To all whom it may concern:

Be it known that we, FRANK A. CASTEEL and ROBERT M. MAYFIELD, citizensof the of whichthe following is a specification.

tit

The means usually employed for attach ing miners lamps to miners hats orcaps ad-.

mit of the lamps having a play which is annoying and otherwiseobjectionable because of the jar occasioned by the swaying or lateralvibratory, movement of the lamp;

resulting from the natural movements of the miner when at work.

This invention provides securing means for the miners lamp which, whileadmitting of the lamp being placed in position upon the hat or cap orremoved therefrom with the greatest facility bythe usual slip-joint,

will at the same tune prevent any play or movement of the lamp whenattached to the hat or cap, thereby avoiding the jar, incon venience andother annoyance usually experienced by the ordinary joint which, permitsof the lamp having a swaying movement and lateral play.

iflhe invention consists of the novel and pedtiliar joint between thelamp and the bracket attached to the hat or cap, such joint admitting ofplacing the lamp in position or removing it from the cap in the ordinaryway but which joint will be free from any lateral play and hold the lamprigid.

The'invention also consists of the unique form of bracket embodying asocket formed in such a manner as to coact with the lug of the lamp topreclude any possible swaying of the lamp when the latter is placed inposition on the hat or cap.

The invention furthermore consists of the novel features, details ofconstruction and combinations of parts which hereinafter will be moreparticularly set forth, illustrated and claimed.

In the drawings hereto attached: Figure 1 is a view in elevation, partsbeing broken away, of means for attaching a miners lamp to a miners hator cap embodying the invention. Fig. 2 is a horizontal section of thelamp attaching means, the lamp being indicated in full lines. Fig. 3 isa perspective view of the bracket as seen from the rear.

'portion of the bracket as seen from the front. Fig. 5 is a perspectiveview of a portion of a minerslamp showing more clearly the lug attachedthereto for cooperation with the socket of the bracket. Fig. 6 is adetail section of a modification.

, Corresponding and like parts are referred to in the followingdescription and indicated. in all the views of the accompanying drawingsby the same reference characters.

The bracket which is attached to the hat or cap comprises members 1, 2and 3, corresponding respectively 'to the crown, body and Vizor, or brimof the hat. This bracket is preferably constructed of sheet material,such as metal, so as to be light and resilient.

Opposite edge portions of the component parts of the bracket arereinforced, as indicated at 3 such reinforcements consisting of edgeportions of the blank from which the bracket is formed being folded uponthemselves. In the preferable construction the crown member 1 of thebracket is in a slightly lower plane than the upper edge of the bodymember 2, thereby leaving a projecting portion 4. extending verticallyabove the forward portion of the part 1. The vertically extendingportion 4 is formed by folding the blank upon itself and then bendingthe part 1 outwardly from the part 2 a short distance from the foldededge, as indicated most clearly in Fig. 3. A socket 5 is formed in theupper portion of thever tical or crown part 20f the bracket and isadapted to receive the lug carried by the lamp. The socket 5 istransversely elongated, as shown most clearly in Fig. 2, and iscomparatively narrow between its front and rear walls. The length of thesocket is such as to insure a firm. and substantial connection beingobtained between the co operating parts, such as the socket and lug,comprising the joint. The body portion 2 of the bracket constitutes thefront wall of the socket. The rear'wall of the socket is .the socket areresilient, hence are adapted to formed by means of a strip of sheetmatelot yield to. admit of the lug being pressed into the socket so asto obtain a snug fit therein and prevent any possible play or movement.While it is contemplated to secure the strip Bto the bracket in anymanner, yet it is preferred to attach the same by means of the foldededge portions 3*, thereby simplifying the const uction and avoiding thenecessity for utilizing extraneous fastening means. A verticallyextending slot 8 is formed in the front wall of the socket'and opensthrough the upper edge of the part 2', thereby adv mitting of the lampbeing placed in position or removed from the socket by meansof aslip-joint. The slot 8 is'open at its upper end and the vertical wallsdefining uch slot are flared at their upper ends, as indicated at 9,thereby giving aflare to the entrance,

.end of the slot so as to direct the lug into the socket and slot whenplacingfthe lamp in position. I

The lug attached to the lamp comprises a web 10 and a plate 11. relativevertical arrangement and. is of a width corresponding to the width ofthe slot 8 so as to fit such slot snugly. One edge of the web 10 isjoined to the rear wall of the lamp 152. The opposite vertical edge ofthe web 10 has the plate 11 joined thereto, such plate projectingequidistant from opposite sides of the web 10,, hence such web occupiesa medial position. to enter the socket 5 and 'fit the same snugly. Theplate 11 by reason of its function may be designated as the.socket-plate and its lower end projects below the web 10 and is madetapering, as indicated at 13, so as to readily enter the upper end ofthe socket 5.

The thickness of the socket-plate 11 corresponds to the-distance betweenthe front and rearwalls of the socket 5 to insure a snug fit betweensuch plate and the walls of the socket, thereby preventing any possibleplay .be pressed together so that when the lug is slipped into thesocket the plate 11 will press such walls apart and as a result theinward tendency of the front and rear walls of the socket to cometogether will create sufficient friction ,on the socket-plate 11 toprevent any possible movement or displacement ofthe lamp.

' In the modification shown in Fig. 6 the crown portion 1 of the bracketis in the plane The web 10 has a.

The plate 11 is designed 5 is open throughout its length of the bodyportion, hence" the receiving end of the socket 5 is in the plane of thecrown portion of the bracket. The vertically extend1ngportion4 isadapted to engage the lower end of the socket-plate 11 and therebydirect such plate to the socket when moving the lamp laterally along theupper part of the bracket, such tapered. end of the plate. 11 droppinginto thesocket when registering therewith. It is to be understood thatthe invention may be applied to the various types of miners lamps andhats or caps, 1 hence when adapting the invention to a particular styleof lamp or head covering, it is to be understood'that various changes inthe form, proportion and minor details of con-L struction may beresorted to within the scope of the invention as claimed, withoutdepart;2'

ingfrom theessential features thereof.

Having thus described the invention what 5 is claimed as new is I 1.Means-for attaching a miners lamp to a miners hat or cap, the samecomprising a member having a transversely elongated socket formedbetween two walls which are resilient to yield, one of such Walls beingformed with a relatively vertically extending slot which is open at itsupper end, and a lug attached to the lamp and comprising a socket-plateand a web to enter and fit within the open-ended slot formed in the wallof the socket.
